Sample questions
-
1.Assertion (A): The elastic potential energy stored per unit volume of a stretched wire equals (1/2) x stress x strain. Reason (R): Work is done against inter-atomic forces when a wire is put under tensile stress and this work is stored as elastic potential energy.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
2.Why is stress, unlike force, not a vector quantity?
- A.because stress has no magnitude
- B.because stress cannot be assigned a specific direction
- C.because stress is always zero
- D.because stress depends on time

3.A structural steel rod of radius 10 mm and length 1.0 m is stretched by a 100 kN (1.0 x 10^5 N) force. Young's modulus of steel is 2.0 x 10^11 N m^-2. The tensile stress is 3.18 x 10^8 N m^-2. Calculate the elongation of the rod. (Take pi = 3.14)
- A.1.59 x 10^-3 m
- B.1.59 x 10^-2 m
- C.3.18 x 10^-3 m
- D.0.80 x 10^-3 m
-
4.A copper wire of length 2.2 m and a steel wire of length 1.6 m, both of diameter 3.0 mm, are connected end to end. A load stretches the combination so that the net elongation is 0.70 mm. Young's modulus: copper = 1.1 x 10^11 N m^-2, steel = 2.0 x 10^11 N m^-2. Obtain the load applied. (Take pi = 3.14)
- A.3.6 x 10^2 N
- B.0.9 x 10^2 N
- C.7.0 x 10^2 N
- D.1.8 x 10^2 N
-
5.A steel cable of radius 1.5 cm supports a chairlift. If the maximum stress is not to exceed 10^8 N m-2, the maximum load the cable can support is approximately:
- A.7.1 x 10^4 N
- B.7.1 x 10^3 N
- C.1.4 x 10^5 N
- D.3.5 x 10^4 N
